Onewheel Plus XR Charge Time? Charger compatibility?

Also, FM is really kinda shady when it comes to their charging time specs on their website. For the the original and the plus, they quoted a 20 minute charge time, but the actual charge time was 42 minutes, from a fully drained battery. Even though their website claimed a "20 min full recharge" for the plus in 20 minutes. Here is a link to a way back machine showing the quoted specs: https://web.archive.org/web/20170128033521/https://onewheel.com/products/onewheel-plus-silver-edition
I asked FM about the charge time for the original, which had the same charge specs as the plus, and this was their response.

In my opinion, it would probably be acceptable to say that you have a “full” charge in 40 >minutes, instead of 42. But not 20. That is clearly a lie.

If it said “20 minute average charge time” that would be acceptable.
Why does your website claim a FULL charge in 20 minutes? Full charge is 0% - 100%.

Your website says, and I quote, “20 minute full recharge.” Full recharge means the board is >completely discharged, and charged. My board only charges to 50% in 20 minutes.
Is something wrong with my board? If not, is something wrong with the information you >are providing on your website?

Not really a BIG deal, but they were definitely peddling misleading specs on their website regarding charge time for the plus. Even with the XR, they quote a "fast charge." 110 min is simply NOT fast.
You can search the forum and find other cases where others were also showing charge times for the plus that were double what was advertised on their website.
I still love my board, but maybe itll be better to wait for an actual gen 2. They just need to use higher wattage chargers and they can get the charge time on the XR to at most 60 minutes, if not 40 like the plus.

@corlux I agree.
Advertisement should be something along the lines
20 minutes from 0 to 80%
40 minutes to 100%
funny how they just blatantly ignored the false advertisement comment.
All in all, FM isnt the best when it comes to PR, and communication. (They hit home with a product that made them grow way larger than they imagined). Hopefully this is a temporary phase in their life as a company.

REAL 20 min charge time would certainly reduce the number of times you could charge the battery and have it keep the full charge as spec’d (ie, number of cycles of charging where the battery still provides most of it’s rated capacity).
The slower you charge a battery like this the longer it lasts. Once you charge past 1C (accelerated charging), you can reduce the life of the battery. So there’s a trade off...I would love a “real”, “full” 20 min charge also, but I’d rather not replace the battery sooner than it’s rated cycles indicate. That could be $500 or more for a new battery. See what 18 or 20 Panasonic high capacity 18650 cells cost - it’s about that much.

Most LFP can actually handle a 3C (20 min) charge. ~16 min in constant current, ~4 min in constant voltage. Cycle life is still fine, but energy density is low, depending on how they tune the electrodes. Also, this is really more about the accuracy of FM statements, as they did claim a FULL charge on the website. Full means from 0% state of charge to 100% state of charge (SOC) If they had said something like "average charge is 20 minutes" that would have been more accurate.
Just makes me cringe a little wondering what to expect with the XR. Especially since, as of this writing, their main claim is that the XR has a FAST charge, when the charge is really 110 freaking minutes.
What happens when customers buy the XR expecting FAST to mean 20 minutes, instead of 110 minutes?
Pretty freaking shady...
That's it. I've convinced myself. Order canceled. Lol.

$8 apiece for the original cells (provided you buy 1000 ― 62 packs).
That's $128 for a 16 cells battery pack. :)

Great find! Those are the original batteries? Are we sure it isn’t a 2P configuration though (ie, 32 batteries)? Also, those are only 2500 Mah and the ones I saw on amazon were 3400-3500 Mah.
At any rate, I’ve used A123 batteries in my electric rc planes (not for high power stuff, but for receiver batteries) and they are great.
But I do also agree that the charge statements by FM are misleading. I’ve been going around telling people “it only takes 20 mins to charge” like an idiot.

If it is a 2 hour charge time, that would be lame. Might just stick with the plus in that case. The thing that still blows my mind is that I'm all charged up from 0% in about 25 minutes.

Seen this morning that they did use NMC cell batteries.

I got my OW+ end December 2017. First i was like Nooooo new one XR, than find out that will take 110min (still not proved yet) vs 20-40min charge. I am good with my OW+ with my car inverted charger on rd.
Noticed: OW website are skipping timing charge for XR, only say "Fast Charge" https://onewheel.com/products/onewheel-xr.

as long as FM got a little more honest with us about this 110mins (@Julian has backed up the charging statement in the XR release thread)..
If you have an XR and charge it for about 37 mins it should give you about 5 miles in range, yes? (Ballparking a 15 mi total) 110÷3=36.6
With the +, 5 miles is close to what that charge time would get you (depending on weight, terrain, psi, temp, towing a skateboarder, etc)
40 min gets you 6mi and that's ok
<40 min × 3 gets you 17 and that oughtta be ok too but nooOoo.
Sounds fair to me
It's like having two whole additional batteries for your + that you don't have to swap or carry. Neat
